At 17:30 23 November 2003, Milan Air asked for help
finding an article on removing old contest numbers...

RAS readers were kind enough to tackle this and a related
question about rubbing compound back on March 20,2003.
Searching on 'contest number,' the rec.aviation.soaring
archive link on the Glider Pilot Network can take you
to these suggestions.

FWIW: Lacquer thinner worked for me, so although I
did not find Gary Evans sanding advice necessary, I
firmly believe the case of beer he suggested is an
integral part of any project.... asuming, of course,
it's reserved for the post-project celebration.

I've removed factory painted on numbers from a couple of Libelles.
Laquer thinner works, but it is actually the acetone component of laquer
thinner that does the job. Straight acetone actually works a lot better
than the laquer thinner and is cheaper and less toxic.
